This paper presents a numerical model for non-linear analyze steel-concrete composite beam subjected to monotonic and repeated loading with partial and full interaction. The model is constructed by a modified FORTRAN computer program. The nonlinear responsiveness for the composite beam is depending on dividing the element into fibers using a section layered method with the constituent materials hysteretic models. A derivation of the cyclic model for the concrete, reinforcing bar and profile steel has been adopted. The behavior of the shear connectors under repeated load has also been derived. Since the slip between the components of composite beams is considered as a basic factor in the analysis, a slip model is adopted to estimate its amount. The numerical model is validated using experimental results. The results indicate that the presented numerical model can provide an effective tool for analyzing steel-concrete composite beam
